PhD Vision, Speech and Signal Processing
At the Centre for Vision, Speech and Signal Processing (CVSSP), we’re developing exciting and ground-breaking technologies. These include facial recognition for security and medical imaging, and 3D spatial audio and 3D reconstruction from video for visual-effects production in films, games and virtual reality.
Why choose this
programme?
Our research is creating machines that can see, hear and understand the world around them.
CVSSP is one of the largest audio and vision research groups in Europe, and we’re internationally recognised for our pioneering research and novel technologies in audio-visual machine perception. We bring together a unique combination of cutting-edge sound and vision expertise with more than 170 researchers, and we’ve currently attracted more than £30 million in research grants.
Our research aims to advance the state of the art in audio-visual signal processing, computer vision and machine learning, with a focus on image, video and audio applications. We have expertise and activities in computer vision, digital signal processing, machine learning and artificial intelligence, computer graphics and human computer interaction, and data science for media, medical image analysis and multimedia communication.
We often collaborate with industry and our research has led to frequent technology transfer and exploitation, with previous research projects having resulted in award-winning spin-out companies in biometrics, communications and medical technologies, and in the creative industries.
In the Research Excellence Framework (REF) 2021, the University of Surrey ranks 15th in the UK for research power for engineering and top 20 in the UK for the overall quality of research outputs (research papers and other published works).
What you will study
Our PhD programme takes a maximum of four years of full-time study to complete. After 12 months, you’ll write a confirmation report, which is assessed by two independent examiners. After that, you’ll submit a written PhD thesis after a minimum of three years of full-time study.
You’ll be allocated two Surrey-based academic supervisors, in addition to any external collaborative supervisors. Your principal supervisor will be an expert in your area of research and they will monitor your research progress on a regular basis. Your supervisors will help you define the initial objective and scope of your research, and to refine these as your project evolves. They’ll direct you to resources and they’ll be able to advise you on how to complete your PhD and your thesis. We often appoint external collaborative supervisors to contribute specific expertise or to allow access to external resources or organisations.
You’ll also be assigned to a research group that includes a team of academics, postdoctoral researchers, guest scientists and fellows. Lots of our research at CVSSP is interdisciplinary and you’ll have the opportunity to collaborate with scientists at universities, research establishments and industries around the world. We encourage active interaction with your peers and our researchers and academics, and we offer a friendly environment that nurtures openness and collaboration. You’ll be encouraged to present your research at renowned national and international conferences to gain experience and establish networks with leading researchers.
Our monthly seminars are open to all postgraduate researchers and we host leading experts from other institutions within the UK and from overseas, who give talks to members of CVSSP in specific areas of research. In addition, our postgraduate researchers also attend regular internal seminars, where you’ll be able to present your individual research or practice presentations you’d like to give at conferences or events.
The University also holds an annual postgraduate researcher conference on campus, where you’ll be able to showcase your work and network with other researchers and academics.
You may be eligible to apply for membership with the British Machine Vision Association, the Audio Engineering Society, the British Computer Society and the Institute of Engineering and Technology. You may also apply for chartered engineer status with the Engineering Council UK and with the Institute of Electrical and Electronics Engineers.
Assessment
Your final assessment will be based on the presentation of your research in a written thesis, which will be discussed in a viva examination with at least two examiners. You have the option of preparing your thesis as a monograph (one large volume in chapter form) or in publication format (including chapters written for publication), subject to the approval of your supervisors.
Location
This course is based at Stag Hill campus. Stag Hill is the University's main campus and where the majority of our courses are taught.

Research support
The professional development of postgraduate researchers is supported by the Doctoral College, which provides training in essential skills through its Researcher Development Programme of workshops, mentoring and coaching. A dedicated postgraduate careers and employability team will help you prepare for a successful career after the completion of your PhD.
Facilities
We host a number of cutting-edge laboratory facilities in CVSSP to support the exciting research being carried out by all its members and associates.
4D computer vision
The Audio-Visual Lab hosts a state-of-the-art capture studio with unique multiple UltraHD cameras supporting research in real-time audio-visual processing and visualisation. We collaborate with companies specialising in film, TV, games, and virtual and augmented reality.
Spatial audio and machine audition
The Audio Lab facilities include a purpose-built audio booth and the Surrey Sound Sphere, which is the centrepiece of our cutting-edge audio and acoustics research. It includes 64 Genelec speakers with audio interfaces, 48 configurable channels, a pre-amplified microphone array and an acoustically isolated audio booth.
The Surrey Sound Sphere has supported research on personal sound zones, human sound localisation and object-based 3D spatial audio as part of the S3A research collaboration. This is supported by the Engineering and Physical Sciences Research Council (EPSRC).
Biometrics and face recognition
We have state-of-the-art equipment supporting research into 3D face recognition, including facial feature types, emotion recognition and face models for biometrics. This was part of the FACER2VM EPSRC Programme Grant.
